SPECIFICATION forming part of Application filed June 29, 1896. Serial No. 597,386.

To all whom it may concern.-

Be it known that we, JOHN STAPLES and VILLIAM l-I. SPAKE, citizens of the United States, residing at Ennis, iu the county of Ellis and State of Texas, have invented a new i to provide simple and efficient meansfor ad-v justing the position of the wheel to suit the direction of the wind. 7

Further objects and advantages of this invention will appear in the following description, and the novel features thereof will be particularly pointed out in the appended claim.

In the drawings, Figure 1 is a perspective view of a churn-motor constructed in accordance with our invention. Fig. 2 is a partial sectional view of the same. Fig. 3 is a rear view of the wheel.

Similar numerals of reference indicate corresponding parts in all the figures ofthe drawings. H i

1 designates a base upon which is swiveled a vertical standard 2, which is adapted to rotate freely for a purpose hereinafter explained. The standard is reduced at its lower end to fit in the bearing 3 at the center of the base and similarly to fit in a bearing at, formed in a cap 5, and attached to this cap are guys 6 to prevent lateral deflection or vibration due to the pressure of the wind.

Extending rearwardly from the swiveled upright is a bracket-arm 7, ;upon which is mounted a driving-shaft 8, carrying a windwheel 9, and extending forwardly from the upright is a support or platform 10 for a ohurn receptacle 11, whereby the weight of the churnaeccptacle is at the opposite side of the upright from the wind-wheel and tends to counterbalance the same.

The means illustrated in the drawings for comm unicatin g motion from the drivin g-sh aft to the churn-dasher 12 consists of a vertical reduced at its upper end Letters Patent No. 593,000, dated November 2, 1897.

(N0 model.)

slide 13, mounted in upper and lower guides 14, and a pitman l5, connecting said slide with a crank-arm 16 on the front end of the driving-shaft.

Inasmuch as the upright is free to rotate and the wind-wheel is arranged upon an arm extending rearwardly from the upright, said wind-wheel facing the upright, it will be seen that the pressure of the wind upon the windwheel will turn the upright without the use of a vane until the faces or front sides of the wind-wheel blades are directly opposed to the direction of the wind. Furthermore, inasmuch as the devices carried by the upright are arranged to counterbalance each other and the cap is secured to prevent lateral vibration of the upright by reason of the pressure of the wind, it will be seen that the upright will turn freely to allow the vaneless wind-wheel to receive the full pressure of the wind.

In order to adapt the wind-wheel for use at a comparatively slight elevation and enable it to. be turned with sufiicient power to properly operate the churn-dasher, we preferably construct the blades in the axially-elongated form illustrated. The blades are secured centrally to the arms of the spider 17, and the front and rear edges of the blades extend approximatelyradially from the center of the spider, the outer edges of the blades being curved approximately concentrically with the points of intersection of the front and rear edges. In order to provide for securing the wheel against rotation when not in use, we employ a hook 18 for engaging a perforation 19 in the contiguous extremity of one of the blades.

Various changes in the form, proportion, and the minor details of construction maybe resorted to without departing from the spirit or sacrificing any of the advantages of this invention.

Having described our claim is- Y A churning apparatus comprising a stationary base, a stationary bearing-cap arranged above the base, a vertical rotatable standard swiveled at its extremities respectively in said base and cap, said standard being provided at its lower end with a laterally-extending support or platform movable therewith and invention, what we adapted. to support a churn-receptacle, and at a point intermediate its ends with an off standing bracket-arm arranged at the side of the standard opposite said support or platform, a shaft journaled on said bracket-arm, a Vaneless Wind-Wheel mounted on the outer extremity of said shaft and having one or more of its blades provided with a perforation,

dasher-operating mechanism mounted on the standard and having a connection With the inner end of said shaft, and a hook mounted on the standard and adapted to engage with the perforation in the contiguous Wheel-blade, substantially as set forth.

In testimony that We claim the foregoing as I 5 our own We have hereto affixed our signatures in the presence of two Witnesses.
